 - **S3 Tables API (Iceberg Support)**: Extensive support for Iceberg tables, namespaces, and buckets.
     - `CreateTableBucket`, `ListTableBuckets`, `GetTableBucket`, `DeleteTableBucket`, `CreateNamespace`, `CreateTable`, etc.
 - **Bucket Management**: SeaweedFS implements `PublicAccessBlock` and `OwnershipControls` which are rejected or labeled as dummy in some MinIO versions.
+- **Object Rename**: `RenameObject` renames an object atomically without copying its data. AWS offers this API only on directory buckets (S3 Express One Zone); SeaweedFS supports it on regular buckets. See [[S3 RenameObject]].
